As a genus, Brontosaurus existed for a long span of time, and have been found in most levels of the Morrison.
A gene is a basic unit of heredity in a living organism that normally resides in long strands of DNA called chromosomes. Genes are coded instructions that decide what the organism is like, how it behaves in its environment and how it survives.
The difference between DNA and a chromosome has to deal with an intermediary-genes. DNA is deoxyribonucleic acid, which is a nucleic acid. It is made up of four bases-adenin â¦ e, cytosine, guanine and thymine.When these four bases are arranged in a segment, it is called a gene. gene is not a single structure or thing. It is made up of the micro-structures that determine a trait. These micro-structures are primarily chromosomes. Chromosomes are pieces of DNA.
